Iran's electricity network has lost around 4.2 gigawatts of capacity following U.S. attacks, with damage to the country's power infrastructure exceeding 60 trillion tomans ($1.5 billion), according to the head of state-run utility Tavanir.

Mohammad Elahdad, Tavanir's chief executive, said the attacks damaged more than 2,000 locations across the national grid, cutting available capacity by about 4,200 megawatts and putting additional strain on the system as summer electricity demand climbs.

Before the conflict, Iran had an installed electricity generation capacity of 98,802 megawatts, according to Iran Power Generation, meaning the reported loss represents about 4.3% of the country's generating capacity.

Iran urges households to save electricity

In a statement carried by Iran's ISNA News Agency, Elahdad said keeping the grid stable in the coming days will depend on careful load management and public cooperation as crews repair damaged infrastructure.

He warned that soaring temperatures have driven up electricity demand while reducing the efficiency of power equipment, adding further strain to the grid and repair teams.

Elahdad said the electricity sector has mobilized all available resources to restore the network, urging households to use cooling systems efficiently and avoid unnecessary electricity consumption during the peak summer period.

Iran's power grid bears brunt

Iranian officials have repeatedly acknowledged that power plants, substations, transmission lines and other electricity infrastructure were among the targets during the months-long campaign.

Earlier in June, Deputy Energy Minister Mostafa Rajabi Mashhadi said more than 7,000 megawatts of generating capacity had been damaged during the conflict, although over 2,500 megawatts had already been restored. He estimated the damage affected about 7% of Iran's installed power generation capacity.

U.S. President Donald Trump repeatedly threatened to target Iran's electricity network earlier in the conflict, warning that U.S. forces would "obliterate" the country's power plants if Tehran refused to reopen the Strait of Hormuz or comply with Washington's demands.
